Check Digit Verification of cas no
The CAS Registry Mumber 125941-69-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,9,4 and 1 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 125941-69:
(8*1)+(7*2)+(6*5)+(5*9)+(4*4)+(3*1)+(2*6)+(1*9)=137
137 % 10 = 7
So 125941-69-7 is a valid CAS Registry Number.
